Installation

(See project on npm)

How to use

Setup

Running the Arethusa widget requires serving some static JavaScript and CSS files. The easiest way to do this is to link the files from node_modules to a directory in your application that serves static files:

cd path/to/static/files
ln -s path/to/node_modules/arethusa-widget/dist/arethusa ./arethusa

In the <head> of the HTML file on the page that will contain Arethusa (or for a single page app, the public HTML page) add the following:

<script type="text/javascript" src="/public/url/arethusa/arethusa.packages.min.js"></script>
<script type="text/javascript" src="/public/url/arethusa/arethusa.min.js"></script>
<script type="text/javascript" src="/public/url/arethusa/arethusa.widget.loader.js"></script>
<script type="text/javascript">
  window.i18npath = "/public/url/arethusa/i18n/";
  window.dagred3path = "vendor/dagre-d3/dagre-d3.min.js";
</script>

<link rel="stylesheet" type="text/css" href="/public/url/arethusa/css/arethusa.min.css">
<link rel="stylesheet" type="text/css" href="/public/url/arethusa/css/colorpicker.css">
<link rel="stylesheet" type="text/css" href="/public/url/arethusa/css/font-awesome.min.css">
<link rel="stylesheet" type="text/css" href="/public/url/arethusa/css/foundation-icons.css">
<link rel="stylesheet" type="text/css" href="/public/url/arethusa/css/widget.css">

The /public/url is the base path of the page. For most applications you will probably want to change /public/url to /. If embedding in a React app, change /public/url to %PUBLIC_URL%.

Usage

In the JavaScript file where you would like to use Arethusa, import the ArethusaWrapper. The ArethusaWrapper requires an elementId, which is the id of the HTML element that will hold the treebank, a remoteUrl, which is the equivalent of /public/url/arethusa mentioned above, and a doc which is the URL of a treebank XML file.

Rendering Arethusa requires a configuration. Two ready-to-go configs are provided: defaultConfig and sidepanelConfig. You will also need to provide a sentence and (optionally) a list of words to select.

import { ArethusaWrapper, defaultConfig, sidepanelConfig } from 'arethusa-widget';

const wrapper = new ArethusaWrapper({
  elementId: 'treebank_container', // `id` of the HTML element containing the widget
  remoteUrl: `/arethusa`, // the `/public/url/arethusa`; for React it would be `process.env.PUBLIC_URL + '/arethusa'`
  doc: 'https://www.example.com/treebanks/some_treebank.xml', // URL of the treebank
});

wrapper.render({
  chunk: '1', // sentence of the treebank to display
  config: defaultConfig, // this can be `defaultConfig`, `sidepanelConfig`, or a custom configuration object
  words: [1], // (optional) words to highlight; `1` highlights the first word, `2` the second word, etc.
});

The HTML of the page should contain a <div> with class __artsa which should itself contain a <div>. The id of this second <div> should match the elementId argument passed to new ArethusaWrapper().

<div class="__artsa">
  <div id="treebank_container" />
</div>

The following functions can be used with the instantiated wrapper once it has been rendered:

// Go to another sentence and/or highlight other words
wrapper.gotoSentence({
  chunk: '2', // sentence of the treebank to display
  words: [2,3], // (optional) words to highlight; `1` highlights the first word, `2` the second word, etc.
});

// Return the subdoc (string) of the current sentence
wrapper.getSubdoc();

// Return the morphology (object) of a particular sentence and word
// See https://github.com/alpheios-project/arethusa/blob/widget/app/js/arethusa.core/services/api.js#L59
wrapper.getMorph({
  chunk: '4', // sentence of the treebank to display
  wordId, // a word to select; `1` highlights the first word, `2` the second word, etc.
});

// Refresh the Arethusa view
wrapper.refreshView();

// Given a chunk, word, prefix (optional), and suffix (optional), moves to the
// specified sentence and returns a list of matching words
// See https://github.com/alpheios-project/arethusa/blob/widget/app/js/arethusa.core/services/api.js#L121
wrapper.findWord({
  chunk: '2', // sentence of the treebank to display
  word: 'χαῖρε', // the word to find
  prefix: 'ἀλλὰ', // (optional) prefix the preceding word or words
  suffix: 'ὦ', // (optional) suffix the following word or words
});

(This package is designed to be used with ES6 modules and Webpack. If you do not have that set up for your project you will need to replace the imports with the equivalent requires.)
